孔口联合导流优化计算

本文以导流系统为研究对象,对混凝土大坝的施工导流给以优化计算。文中提出了以围堰费用、底孔封堵水头和施工导流控制工期为目标,以地形、截流、下游供水泄洪以及施工强度为约束的多目标决策模型.并对导流标准引入可接受的风险率概念进行分析确定。运用递推校正法进行多目标的求解计算,最后结合工程实例说明这种方法的有效性。

Optimum Computation of the Bottom-outlets and Openings Combined Diversion

This paper makes a study of the system of construction diversion and the construction diversion optimum computation of the concrete dam. A multiobjective decision model is put forward, with the odjects of the cost of the cofferdam, the head on the bottom outlets when they are closed, and the control period of the construction diversion. Within certain restrictions of geography, closure, flood discharge, and construction intensity, the diversion standard is analysed and anacceptable risk is determined. The recurrence and rectification method is applied to resolve the model. Finally, a typical example of an application of the method in practical engineering is given.
